| Gene Symbol: | FGF23 |
| Gene ID: | 8074 |
| Uniprot ID: | FGF23_HUMAN |
| Specificity: | This kit recognizes Human FGF23 in samples. No significant cross-reactivity or interference between Human FGF23 and analogues was observed. |
| Sample Type: | Serum, plasma and other biological fluids |
| Post Translational Modifications | Following secretion this protein is inactivated by cleavage into a N-terminal fragment and a C-terminal fragment. The processing is effected by proprotein convertases. O-glycosylated at Thr-171 and Thr-178 by GALNT3 and glycosylation of Thr-178 requires previous glycosylation at Thr171. Glycosylation is necessary for secretion.it blocks processing by proprotein convertases when the O-glycan is alpha 2,6-sialylated. Competition between proprotein convertase cleavage and block of cleavage by O-glycosylation determines the level of secreted active FGF23. Phosphorylation at Ser-180 mediated by FAM20C slows down glycosylation at Thr-178 notably. |
| Function | Regulator of phosphate homeostasis. Inhibits renal tubular phosphate transport by reducing SLC34A1 levels. Up-regulates EGR1 expression in the presence of KL. Acts directly on the parathyroid to decrease PTH secretion. Regulator of vitamin-D metabolism. Negatively regulates osteoblast differentiation and matrix mineralization. |
